A Suffolk woman who carried out a vicious attack on her 91-year-old father who suffers from dementia as he sat in a chair has been jailed for two years.

Jill Rouse, who lived with her parents Roy and Doreen Varney in Kestrel Drive, Brandon punched her father in the face, head and groin causing a fracture to his upper jawbone, Ipswich Crown Court heard.

She had then smeared her own faeces over his face and head, said Daniel Taylor, prosecuting.

Rouse, 56, admitted assault causing actual bodily harm and breach of a conditional discharge for two offences of battery.

She was jailed for two years for the assault on her father, with two months to run consecutively for the breach of the conditional discharge.

She was also made the subject of a restraining order banning her from contacting her parents or going to Brandon until further order.

Jailing Rouse, who appeared at court via a prison video link, Judge Rupert Overbury described the attack on her father as “vicious”.

“This was a sustained assault,” he said.

“In my judgement this was the deliberate targeting of a vulnerable man - he couldn’t possibly defend himself from the vicious attack you carried out.

“It was not only vicious but it was also degrading and humiliating by you getting your own faeces and smothering his face with them.”

He said there was also an element of revenge in the attack.

Judge Overbury said that although Rouse had a borderline personality disorder, she did not have mental health problems.

The court heard that during the night before the attack, Rouse’s mother heard her daughter shouting and screaming and saying the devil was telling her what to do.

They had gone back to bed and at 8am, Mrs Varney heard her daughter shouting and screaming again and had called the emergency services.

This caused Rouse’s behaviour to worsen and resulted in her attacking her father who was left shaken by what happened, said Mr Taylor.

Rouse told police she had been bullied and hurt by her family.

She claimed she had exploded on the morning in question and had hit her father because she hated him.

She told police she had slapped her father rather than punching him.

Archie McKay, for Rouse, described her behaviour as a sudden loss of control.
